Now more and more intelligent and electronic tools have entered thousands of households, profoundly changing people's way of life. Although the application of electronic tools is more and more widespread, the importance of hand tools is still irreplaceable in some jobs. The most commonly used hand tools are the screw batch and wrench, whether it is installation, maintenance or parts disassembly, we will need to use various types of wrenches to assist us to complete the work.
The types of wrenches that we are more familiar with may be adjustable wrenches, dual-purpose wrenches, box wrenches, torque wrenches and so on. These wrenches are much the same in the way they are used, and the main difference is different for the use of the situation. Below we will focus on the differences between the use of ordinary wrenches and ratchet wrenches and how to choose the two specifically.
Ordinary wrenches like adjustable wrenches and dual-purpose wrenches, their design structure is relatively simple, are to ensure that the main structure is unchanged, at both ends of the design of different shapes of the wrench, different wrench can be used for different parts, using the lever principle to easily tighten or loosen nuts, bolts and other fastener parts.
Compared with ordinary wrenches, the structural design of ratchet wrenches is much more complicated. First of all, the main head of the ratchet wrench is designed in the ratchet, ratchet claw, spring and other special parts, which can be used for some special conditions. The main design structure of the ratchet is composed of the ratchet body and the isolation sleeve, which is actually a ring with external grooves, and is generally installed on one side of the ratchet body.
Comparison of the characteristics of ordinary wrench and ratchet wrench
1. The operation method of ordinary manual wrench is simple, which is suitable for the elastic operation of most ordinary parts, but the long-term work is more laborious.
2. The ratchet wrench has a complex structure, which is suitable for parts that are difficult to be operated by ordinary wrenches, and the head of the ratchet wrench is connected with the main end in a rotating manner.
How to choose the normal wrench and ratchet wrench correctly?
The choice of the two wrenches needs to be determined according to the specific use environment, because there are different tension and torque between different types of wrenches, and the shape of the parts that need to be operated also determines the head shape of the selected wrench. Therefore, we need to comprehensively consider a variety of actual use factors to achieve the correct choice of wrenches, so as to maximize the work efficiency.
